PATENT DOOR-CONTROLLING DEVICE Application fil'ed August 8 1924. Serial No. 730,891.

This invention relates to door-controlling devices and particularly to door-controlling devices especially adapted for use on rage doors which will hold the same open or shut as desired. p V

The chief object of the invention is to provide simple and inexpensive but highly efficient devices of the above described type which will be adapted for easy attachment to the doorsand the frame thereof in such a manner that it will be disposed within the building so as to be protected from the weather, but will permit opening or closing of the doors from the ouside without the necessity of providing a third door to the building.

Another object of the invention is to pro vide devices of the above described type which are readily adjustable so as to permit holding of the doors open at various angles, thereby enabling the device to successfully perform its functions under various condition frequently met with in use.

The foregoing and other objects are obtained in the structure disclosed in the accompanying drawings and fully described below, it being understood, however, that the invention is not limited to the specific structure shown and described.

Of the accompanying drawings:

Figure 1 is a front elevation of a device embodying the invention;

Figure 2 is a detail plan of a bracket forming a part of the above device;

Figure 3 is a detail plan of a bracket and swivel forming a part of the above device; and

Figure 4 illustrates the manner of mounting the device for use.

Referring to the drawings, 10 is a bracket adapted to be secured in any suitable manner to the upper part of a door frame as shown in Figure 4. The bracket member 10 preferably is a stamping from sheet steel and has a U-shaped swivel member 11 pivoted thereon, the member 11 being formed.

by a steel stamping bent to the shape shown and provided with a central aperture 12 by which it is adapted to be loosely riveted to the bracket 10 and with aligned apertures 13, 13 in the legs of the U adapted slidably to receive a thrust rod 14.

The rod 14 is straight substantially throughout its length, but is bent at one end to form a portion 15 adapted to engage in any of a series of apertures 16, 16 formed in a bracket lT, which latteris adapted to be secured to a door, as illustrated in Figure 4, adjacent the top thereof and also adja cent its hinged edge. The bracket 17 is preferably formed of a stampingof suitable shape from sheet metal and is bent to Lshape in section as shown, the apertures 16 being in one arm of the L and being arranged along the arc of a circle therein.

The bracket may be perforated in the other armof the L, as shown at 18, so as to adapt it to be screwed to the door in the position shown in Figure 4. To secure portion 15 of rod 14 in any oneof apertures 16, a

cotter pin 19, or other suitable fastening device, maybe employed.

From the. foregoing. it will be apparent that as'the door is opened and closed, the rod 14 will travel back and forth through the apertures 18, 13. In order to control this movement to. hold the door either open or shut, a compression spring 20 is mounted onthe rod. 14 between the swivel member 11 and the door bracket 17, one end of the spring being permitted to abut the swivel member 11 and the other end having a clip 21 secured thereon and adapted to abut a cotter pin 22, or other suitable device se- 0 cured on the rod.

In order to cushion the opening or closing force of the spring 20 on the door, an auxiliary compression spring 23 may be mounted on the rod 14, one end in abutting relation to the swivel member 11 but on the opposite side of the swivel member 11 from the spring 20, a clip 24 being secured on the other end of spring 23 which is arranged to abut a cotter pin 25, or other device, on the rod 14.

In operation, if the door is opened from shut position, the spring 20 is first placed under additional compression, tending to close it. However, after the door passes that position in which the hinge, the aperture 16 in which rod 14 is engaged, and the swivel are in line. the compression spring 20 becomes effective through rod 14 on the other side of the hinge and tends'to continue the opening movement of the door until the compression in the spring is expended. .By placing the portion 15 of rod 14 in one or the other of the apertures 16, the position at which the door will be held open can be varied. The spring 2?) acts to cushion the compressive force in the spring 20 to prevent the door being swung too hard in either direction on lts hlnges.

It will be noted that all parts of the apparatus are easily and cheaply made, and that they are adapted to be so mounted as not to be exposed to the weather when the door is closed. Furthermore, the doors are operable from and may be locked on the outside, thus rendering the provision of another entrance to the garage unnecessary.

Modifications of the invention may be resorted to without departing from the spirit thereof or the scope of the appended claims.

e claim:

1.. A door controlling device comprising a bracket adapted to be attached to a door, a bracket adapted to be attached to a door frame, a swivel member on the second bracket, a rod pivoted on the first bracket and slidably mounted on the swivel member, said first bracket being adapted to pivotally receive said rod in a plurality of positions, and a spring normallyunder compression on the rod between the first bracket and the swivel member.

The combination with a hinged door of a door controlling device comprising a bracket attached to the door, a bracket attached to a door frame, a swivel member on the second bracket, a thrust rod pivoted onto the first bracket and slidable through the swivel member, the pivot on the first bracket being spaced away from the door, whereby the rod Will be directed to one side of the door hinge when the door is closed beyond an intermediate position, and to the other member when the door is moved from either a completely closed position or a completely open position whereby the force of the spring will be directed to one side of the hinge to shut the door when the latter on one side of the intermediate position and will be directed to the other side of the hinge to open the door when the door is on the other side of the intermediate position.

3. In a device of the class described, a thrust rod adapted to be pivoted to a door, and a swivel member adapted to be secured on a door frame and to slidably receive said rod, said swivel member comprising a strip of sheet metal bent to substantially U-shape and formed with aligned apertures in the legs of the U.

In a device oi the class described, a thrust rod slidably mounted and swiveled onto a door frame, said rod being formed with a bent end, and a bracket mounted on a door, said bracket having an aperture therein for the reception of the bent end of said rod.
